英语短文改错my senior year in high school was
my senior year in high school was a particular stressful one.My mother had just died with cancer ,and i knew it would be difficult to deal with this loss.One day ,after spend many hours studying for my finals,i checked my mailbox.To my surprise,i found two ticket for a concert next evening .There was a note attacher what said ,"Relax and enjoy yourself!"No name ,but no return address.
i was very happy and felt even better just knowing that someone had noticed how difficult that the changes in my life had been.i had no idea who was such kind ,but whoever helped me deserved his sincere thanks.
